Project Balance 3.0 mod
Started as a ruler designer Count of Kaliopolis (Age 29, traits: Grey Eminence, Legitimized Bastard, Patient, Lustful, Trusting). I revoked the city and temple baronies from my two vassals, and sat my steward on my county to collect taxes. Saved up all of my money, and waited until January 1072 when the Seljuk-Byzantine War ended. The plot to fabricate a claim on Thrace went off without needing to bribe anyone, and had plenty of plot power. The plot to acquire it however, was tougher.
I went to work, and spent the better part of 250 gold on bribes, getting several swing backers, and having 2 people with a green thumbs-up with no bribes. My backers weren't exactly powerful, in my mind. Mostly the smaller dukes, and a count. The Basileus would still have 6k levies or so, plus the 3k Varangian Guard, against ~3-4k rebel troops. He could've squashed me in a war attempt.
But no, he was scared of the little count next door.
